If this is true, and I am not saying it is or isn't, then I am going to have to assume it is that 3rd bit number of 1,099,511,627,776. I would also have to assume it would be something in the software, OS, BIOS, etc, and not in the hardware (3 extra bits is just not normal). My guess would be in the old FreeBSD it is based on and how it handles the software RAID 5. I would be VERY interested to know if it will do a RAID 0 over this boundary. Not that anyone really wants to use RAID 0 in a SNAP, but this would tell us a little something in the investigation.

I myself have seen 1 TB Snap 4000's for sale on ebay and people using them elsewhere, so I have to assume 1 TB is okay and it would fit in with being below the 1,099,511,627,776 number above. Has anyone seen a Snap 4000 in RAID 5 over 1 TB?

Another interesting point that may or may not make a difference here is the versions of the 4000. There are 4 versions of the 4000 using 3 different revs of the main circuit board. I wonder if there is any difference there either?

Damn I hate it when our conversations ends this way, and they do way too often. An unknown boundry that we can't figure out due to lack of information from the designers. So I will ask again in case someone missed it. Has anyone seen a Snap 4000 in raid 5 above 1,099,511,627,776 bytes?
